Abstract:
Super Ohtaka® (fermented beverage of plant extracts) is prepared from approximately 50 vegetables and fruits. Natural fermentation is primarily performed using lactic acid bacteria (Leuconostoc spp.) and yeast (Zygosaccharomyces spp.). An unidentified oligosaccharide was isolated from this beverage using carbon-Celite® column chromatography and high performance liquid chromatography. The oligosaccharide structure was confirmed by MALDI-TOF MS and NMR measurements. This oligosaccharide was identified as β-D-fructopyranosyl-(2→6)-β-D-glucopyranosyl-(1→6)-D-glucose, it was newly found from natural source. We speculated that this oligosaccharide was generated or enhanced during the fermentation, and was barely degraded by artificial gastric juice and rat intestinal enzymes, although it was slightly hydrolyzed by pig pancreatic enzymes.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
